A lot of our biases come, I think, from expecting real life to be like fiction. For example, when we have negative opinions on important subjects, we tend too much to expect that we should explicitly and directly express those negative opinions in a dramatic conversation scene. We should speak our mind, make it clear, talk it through, etc. This usually a bad idea. We also tend to feel bad about ourselves when we notice that we avoid confrontation, and back off when from things we want when we encounter resistance. But such retreat is usually for the best.
